Abstract
Description
Technical Field
[0001] The utility model relates to a tower-type material mixing and reducing equipment, in particular to a tower-type combined mixing and reducing device. Background Art
[0002] Iron ore, coal, alloy, etc. are important raw materials in the iron and steel industry. When conducting inspections, they need to be crushed, then mixed evenly multiple times and reduced to the required sample amount before being subjected to chemical analysis and testing.
[0003] To reduce the deviation in raw material sample preparation and chemical analysis, the preparation of samples requires thorough mixing of the materials. The vast majority of enterprises first use a traditional riffle divider to mix evenly more than three times, and then reduce the sample multiple times to finally achieve strong representativeness in sample preparation and meet the sample amount requirements for sample preparation. The traditional riffle divider (as shown in Figure 1 ) mostly has a monomer structure. Below the riffle divider 01, there are respectively provided a sample collection tank 8 and a waste collection tank 9. It is necessary to go through three times of splitting and mixing: The first mixing: Pour the prepared materials into the 01 inlet. The materials are split in multiple dividing slots inside the 01, and after splitting, they respectively slide into the following collection tank 8 and waste collection tank 9. The second mixing: Pour the materials in the collection tank 8 and the waste collection tank 9 after the first operation together, and pour them into the 01 inlet again. The materials are split in multiple dividing slots inside the 01, and after splitting, they respectively slide into the following collection tank 8 and waste collection tank 9. The third mixing: Pour the materials in the collection tank 8 and the waste collection tank 9 after the second operation together, and pour them into the 01 inlet again. The materials are split in multiple dividing slots inside the 01, and after splitting, they respectively slide into the following collection tank 8 and waste collection tank 9.
[0004] After completing the above three times of mixing, the reduction starts. The materials that slide into the following collection tank 8 and waste collection tank 9 after the third mixing have completed the first reduction. Then, the materials in the waste collection tank 9 are discarded. At this time, the sample amount of the materials is reduced by 1 / 2. Pour the materials in the collection tank 8 into the 01 inlet. The materials are split in multiple dividing slots inside the 01, and after splitting, they respectively slide into the following collection tank 8 and waste collection tank 9. This process completes the second reduction. Then, the materials in the waste collection tank 9 are discarded. At this time, the sample amount of the materials is reduced by 1 / 2 again. After the above three times of mixing and two times of reduction, the mixing and reduction work is completed.
[0005] The traditional riffle divider mostly has a monomer structure. When mixing and reducing materials, it requires multiple operations by personnel to achieve the purpose of mixing and reducing. It has the disadvantages of cumbersome operation, long process time, low operation efficiency, and large physical consumption of operators. Content of the Utility Model

[0018] Embodiment: When the present utility model is in operation, first, the material is poured from the inlet at the top of the fixed mixer 1, and after being divided by multiple dividing grooves inside the fixed mixer 1, the first mixing is completed. The material after the first mixing falls into the first mixer 2 that simulates the reciprocating motion of manual labor, and after being divided by multiple dividing grooves, the second mixing is completed. The material after the second mixing falls into the second mixer 3 that simulates the reciprocating motion of manual labor, and after being divided by multiple dividing grooves, the third mixing is completed. The material after the third mixing falls into the first-stage quartering device 7 and is divided by multiple dividing grooves to complete the first sample reduction.

[0022] 2. The work efficiency is improved, and the labor intensity of the operators is reduced. See the following table:
